/etc/resolv.conf gets removed on shutdown/startup #6977

TotiTolvukall · 2021-05-22T16:39:03Z

Environment

Windows build number: 21387.co_release.210518-1436 / 10.0.21387.1
Your Distribution version: Ubuntu 20.04
Your WSLg version: [Open 'Apps and Features' and check the version of 'Windows Subsystem for Linux GUI app support', e.g: 0.2.3.13]

Steps to reproduce

Create the /etc/wsl.conf containing the two magic lines:
user@host:/etc$ cat wsl.conf
[network]
generateResolvConf = false
user@host:/etc$

Make sure you have your own resolv.conf:
user@host:/etc$ sudo rm -f resolv.conf && sudo cat > resolv.conf << EOT
nameserver 1.1.1.1
nameserver 8.8.8.8
domain mydomain.com
search mydomain.com
EOT
Password:
user@host:/etc$

In CMD, do a wsl --shutdown

Start WSL Ubuntu 20.04 session again, and check for the /etc/resolv.conf.

It will be gone.

WSL logs:

The wsl logs reveal nothing about resolv.conf

Expected behavior

Expected is that MY resolv.conf is left alone. As it did in the WSL (pre-g release) version.

Actual behavior

Actually my resolv.conf is being forcefully removed - which IS making WSLg unusable until a new one has been put in place.

The text was updated successfully, but these errors were encountered:

spronovo · 2021-05-23T07:48:11Z

Thanks for your report @TotiTolvukall, WSLg doesn't touch this file. This sounds like a possible recent regression in WSL core. @benhillis as fyi.

I'll move this issue to the main WSL github to get this investigated further.

0xbadfca11 · 2021-05-23T11:32:26Z

sudo cat > resolv.conf

Suspicious command line.
Isn't this command line unsuccessful anyway?

TotiTolvukall · 2021-05-23T16:00:40Z

@0xbadfca11 how about at least making an attempt at understanding what's being done before commenting like that?

No, it's not unsuccessful. It's perfectly successful.

try it on a different file.

sudo rm -f filethatdidntexist && sudo cat > filethatdidntexist << EOT
I should have tried this myself before making me look smart on github
EOT

You will be asked for a password - type it in correctly and the SECOND sudo will run without a password.

But THIS is a digression. The original problem is that of resolv.conf being deleted at boot/shutdown and that is what this ticket should address, not script semantics (regardless if you do understand them or not).

SheepReaper · 2021-05-24T01:46:07Z

Check out #5420 (comment) See if that sequence helps

TotiTolvukall · 2021-05-24T10:38:00Z

@SheepReaper the problem isn't the shutdown itself (and I wouldn't have reported it unless I'd tried all kinds of WSL shutdowns - including full computer reboots). The problem is the procedure running (I suspect at start-up, not shutdown as you normally want your autogenerated resolv.conf to be generated from the current settings, not the settings when you last turned off your computer) at start-up. Without having dug into it, my gut feeling tells me;
It should be like this:

if /etc/wsl.conf exists
- if it contains "generateResolvConf" and it's set to "false"
```
: don't do anything
```
- else
```
: delete /etc/resolv.conf
```
```
: symlink to /run/resolvconfsomething
```

But is more like this

delete /etc/resolv.conf
if /etc/wsl.conf exists
- if it contains "generateResolvConf" and it's set to "false"
```
 : don't do anything
```
.
.
.

Just a gut feeling, but it matches up to what I'm seeing.

For now, I have a /etc/resolv.conf.real which is my actual resolv.conf file, and then at EVERY reboot of my computer or fresh startup of WSL, I do "sudo ln -s /etc/resolv.conf.real /etc/resolv.conf"

wjzhou · 2021-06-10T15:23:39Z

I got the same result.

a working workaround for now:
sudo chattr +i /etc/resolv.conf

Full configuration:

# add config to /etc/wsl.conf
# or manually edit if you have other config in wsl.conf
sudo tee /etc/wsl.conf << EOF
[network]
generateResolvConf = false
EOF
# some document says need restart the wsl once for the configure to work
# for me, it works without it, keep it here for reference
# run in windows command
# wsl --shutdown

# /etc/resolv.conf is a symbol link, delete it to create a regular file
sudo rm /etc/resolv.conf
sudo tee /etc/resolv.conf << EOF
nameserver 8.8.8.8
nameserver 8.8.4.4
# search local
EOF

# this is the real bug in wsl GUI version reported here
# for some reason it always delete the /etc/resolv.conf when generateResolvConf = false
# this +i will prevent delete of the file
# to edit the file again please use
# sudo chattr -i /etc/resolv.conf
sudo chattr +i /etc/resolv.conf

The real bug here is that the /etc/resolv.conf file got deleted when generateResolvConf = false. (without creating new file)
So (my guess), there is a delete statement that deletes blinding without checking the generateResolvConf = false option.

But despite the current bug, I still think this whole process needs some design, at least more clear document in /etc/resolv.conf

need to /etc/wsl.conf, the document is clear, so it's ok
some document says need to wsl --shutdown for the option to take effect
need to rm /etc/resolv.conf to remove the symbol link, this step is very easy to forget

Omg, this script worked, thank you very very much

benhillis · 2021-08-10T17:21:29Z

Typically this is happening because /etc/resolv.conf is a symlink to tmpfs. If you want to take ownership of this file, set the /etc/wsl.conf setting, and replace the /etc/resolv.conf symlink with a regular file.

TotiTolvukall · 2021-08-10T17:59:31Z

It would be respectful to ALL the people in this thread @benhillis to at least glance over the discussion so far before replying with an entry that has zero weight.

It has already been concluded that by disabling WSL from messing with the resolver, it removes all traces of resolv.conf - symbolic links as well as regular files. And does so repeatedly (i.e. on every startup/restart.)

Thus the issue.

benhillis · 2021-08-10T19:32:34Z

@TotiTolvukall - I appreciate you taking the time to file this issue, turns out there was some refactoring that introduced this issue. I'll get this sorted out.

This issue has a very common signature of a common pitfall people often run into, I apologize I got this conflated with that one.

bjolivot · 2021-10-18T08:26:42Z

hi!
Any news on that bug ?

trexmaster · 2021-11-15T09:00:54Z

@benhillis any news on this ? I'm also having this issue on Windows 11 build 22000.318

Same problem, Windows 11 build 22000.318

withinboredom · 2021-11-19T21:09:48Z

sudo chattr +i /etc/resolv.conf

keeps the file after a reboot for me. It's not great, but serious kudos for suggesting that!

azilber · 2021-12-07T02:50:47Z

This bug is damn annoying, and open since May, and now has wheedled itself into Windows 11.

nwestra · 2021-12-07T16:47:06Z

I don't recall seeing this behavior in Win10, but definitely confirm this behavior in Win11

SheepReaper · 2021-12-07T20:39:31Z

Not that there aren't valid use cases for specifying /etc/resolv.conf, but the examples above seem to want to use google dns.
Can you not use the default behavior (sets nameserver to hyper-v host network interface) and set your computer's DNS instead? (As a temp workaround, I mean)

nwestra · 2021-12-07T21:05:32Z

For me at some point last year whatever value WSL came up (within the linked resolv.conf) stopped working, so I ended up manually configuring /etc/resolv.conf (telling WSL to leave resolv.conf alone through /etc/wsl.conf).
This worked fine until I made the switch to Windows 11

SheepReaper · 2021-12-07T21:30:18Z

So 2 questions then:

Were you on an insiders build on Win 10 with WSL2?
Did you run wsl --install or wsl --update after upgrading to Win 11?

nwestra · 2021-12-07T21:47:07Z

Nope, regular Win 10 builds from 1909 all the way to 21H2 before upgrading to Win11, at some point upgraded WSL to WSL2, not sure when
Didn't use either, is that required?

udoyhasan · 2022-09-09T11:54:29Z

I was also facing this problem but I fixed it by following steps:

I deleted my default resolv.conf file and created a new one with my custom configurations and after that, I stopped the auto-deleting of the file by giving it read-only permission.

sudo rm /etc/resolv.conf
sudo touch /etc/resolv.conf
sudo echo "nameserver 1.1.1.1" >> /etc/resolv.conf
sudo echo "nameserver 8.8.8.8" >> /etc/resolv.conf
sudo chattr +i /etc/resolv.conf

Then I stop the auto wsl resolv configuration rewrite on startup.

sudo rm /etc/wsl.conf
sudo touch /etc/wsl.conf
sudo echo "[network]\ngenerateResolvConf = false" >> /etc/wsl.conf

Hope this will also fix your issue :)

It's possible this is being ignored (frustratingly, because it should at least be closed if they are going to ignore it...) because the documented solution looks like it works now. I'm not the first user to suggest it here, or the second, but here is more system detail if it helps.

  NAME      STATE           VERSION
* Ubuntu    Running         2

Freshly installed and updated version of WSL2, running freshly-installed Ubuntu (the generic distro, not a specific version) from the Microsoft App Store. Installed WSL itself from Windows, not the App Store. Encountered the common problem where my distro could not connect to the internet. Searching led to #5420, which led to this issue.

Opened the distro, then ran wsl --shutdown in PowerShell in the background
Manually created /etc/wsl.conf and added as suggested in the tip from resolv.conf:

[network]
generateResolvConf = false

Purely to test, closed the distro and reopened it. Now no resolv.conf is created at all, as other users noted.
Shutdown WSL again via PowerShell just in case.
Manually created resolv.conf and added a DNS.

nameserver 1.1.1.1

Closed the distro and reopened it. My custom resolv.conf is still there, and WSL didn't overwrite it. My custom wsl.conf telling WSL not to overwrite resolv.conf is also still there.

Happy to provide any additional system info. Tried to start from as clean a setup as possible.

Not endorsing the fact that Microsoft let the community struggle with this bug for years, just suggesting that the bug may have been quietly fixed by restoring the intended (but still obtuse) behavior of requiring wsl to be shutdown to make sure changes stick.

I did not try a single other intended solution first to preserve integrity, and like many others refused to use the "immutable file" kludge. Hope this helps someone.

luxzg · 2022-12-07T20:22:03Z

As I mentioned about a month and a half ago, like @boner-cmd I have no issues with my custom resolv.conf, and wsl.conf option generateResolvConf = false works for me just fine. But just as described above, I've also started with fresh WSL2 install, on fresh OS, with fresh Ubuntu distro. If someone is still having issues perhaps their workarounds from yesteryear are now working against you. I'm now on 1.0.0 as well, and all works as expected.

lucastheisen · 2022-12-30T14:34:57Z

For me, i was able to get it working again by editing my /etc/resolv.conf then immediately wsl.exe --shutdown. After that it did stick around for next wsl shutdown. Also could be worth mentioning that a resolv.conf is still getting generated at /mnt/wsl/resolv.conf, but it is not replacing mine.

jimklimov · 2023-01-19T15:03:45Z

Thanks for all the suggestions here. Just one pattern repeated by many seems fishy: sudo CMD >> /etc/filename: the redirection >> should be done by your user shell, so unprivileged and unable to write to a system-protected file. I do not know if distros for WSL handle it differently, but in all other OSes people jump through hoops to get such files opened and written by a privileged process - often via cmd | sudo tee (-a) /etc/filename pattern.

Hope this helps :)

I installed WSL through the "Windows Features" checkbox GUI, whatever that does to install WSL.
Note that wsl --version did not work and did not seem to show up in the --help list in this version of WSL I got.

I wanted to avoid sudo chattr +i /etc/resolv.conf.
I used wsl --set-default-version 2 and reinstalled Ubuntu (latest) and still had the same problem.
The fresh install comments suggested to me that I should completely uninstall WSL; did so following this article:
https://pureinfotech.com/uninstall-wsl-windows-11/
I then reinstalled WSL using wsl --install in PowerShell.
Deleted Ubuntu (Default), then reinstalled Ubuntu with wsl --install Ubuntu.

At this point, I am in Ubuntu and manually created the wsl.conf with

[network]
generateResolvConf = false

Exited Ubuntu and did wsl --shutdown.
Went back in and created my custom resolv.conf.
Restarted WSL and ls /etc/ and my resolv.conf was not overridden and still has not after more WSL restarts.

Note that wsl --version did not work and did not seem to show up in the --help list in this version of WSL I got.

For whatever reason, version installed from Microsoft Store is NEWER.

I'd suggest to uninstall WSL, reboot host PC, and install from MS Store.

Running version after that should work. That will also shiw version 1.x.x being installed confirming latest WSL2 version.

From there on just keep updating from Store.

I'm not sure why there's disparity between the installed versions, but several new features are absent as well from non-store versions.

mb555444 · 2023-08-11T08:56:12Z

This bug still exists no matter what. resolv.conf gets deleted from /etc upon shutdown of WSL.

leiflinse-trivector · 2023-08-14T11:52:58Z

I still have the issue and I noticed that for me wsl --version says it doesn't support the --version parameter. I have checked for windows updates.

PS C:\Users\anon> wsl --version
Invalid command line option: --version
Copyright (c) Microsoft Corporation. All rights reserved.

Usage: wsl.exe [Argument] [Options...] [CommandLine]

Reading in wsl --help of this version it seems there is a wsl --update command that updates the wsl engine.

EDIT: After backing up my wsl container I ran wsl --update and now after I created /etc/resolv.conf it does no longer gets deleted when I restart wsl.

TL;DR
If wsl --version does not work, or even if it does, you might be running on an old WSL engine despite having installed all windows updates. To update it, run wsl --update. Then create /etc/resolv.conf once more and it hopefully stays for you too.

SheepReaper · 2023-08-14T17:50:54Z

If `--version` is unsupported, you are using the in-box wsl. You need to install wsl from the M$ Store.

My workaround is to modify "/etc/wsl.conf" first, then do wsl --shutdown, then modify "/etc/resolv.conf". I run a script to install and configure WSL Debian, this solution has worked reliably so far.

This seems to be the solution for now. It would seem that on first wsl reboot after generateResolvConf has been set to false it removes /etc/resolv.conf, but after that it doesn't touch it anymore.

ayushshukla7777 · 2023-12-26T03:47:56Z

Why isn't this getting fixed. Every now and then, I have to spend whole day fixing these issues on wsl. I guess thats why developers are using macbook. Simply- the OS shouldn't come in way of user.

Ya, fix this BASIC functionality. I know we all want to contribute to core kernel but this shit is important too!!

aprescott706 · 2024-03-27T17:42:27Z

Also seeing this issue.

OS: Windows 11
WSL: ubuntu 20.04

/etc/wsl.conf contains
[network]
generateResolvConf = false

I manually create /etc/resolv.conf, shutdown the running instance, start back up and /etc/resolv.conf is gone.

Workaround I'm using is "sudo chattr +i /etc/resolv.conf"

asampal · 2024-03-27T18:38:16Z

@aprescott706 are you using the latest, 2.2.1 at the moment, version of WSL?

aprescott706 · 2024-03-27T18:57:31Z

@aprescott706 are you using the latest, 2.2.1 at the moment, version of WSL?

I'm not sure to be honest. The command wsl --version/-v doesn't work.

File version on wsl.exe is 10.0.22621.1

SheepReaper · 2024-03-27T19:39:34Z

That's because you have the 'in box' version of wsl. You must install wsl from the M$ Store.

easiest way to determine you have the wrong version installed.

when the M$ store version is installed the output is thus:

wsl --version
WSL version: 2.1.5.0

Sometimes, based on issues addressed, you might want to install the latest preview version here, https://github.com/microsoft/WSL/releases. You can find the binaries by expanding the "Assets" section.

I have the version you show here an still had to use the posted workaround. This should not require the suggested workaround. (Taut is what you are suggesting, the workaround was required because the user did not have the latest version?).

Also seeing this issue.

OS: Windows 11 WSL: ubuntu 20.04

/etc/wsl.conf contains [network] generateResolvConf = false

I manually create /etc/resolv.conf, shutdown the running instance, start back up and /etc/resolv.conf is gone.

Workaround I'm using is "sudo chattr +i /etc/resolv.conf"

Same issue, disabled the automatic generation and on restart the file is gone

Still don't know if it's a bug or not. But can confirm that disabling resolv.conf generation does in fact delete it, but only for the first wsl --shutdown for me. If I set generation to false, logout, and then call wsl --shutdown, on the next boot /etc/resolv.conf is missing. But then I can create it, and it persists for every other wsl reboot.

So maybe not bug, but very annoying behavior. Why not just leave the file there even if it was originally generated? (Asking MS here)

My resolv.conf just disappeared randomly. There was no shut-down or restart. I was using it just fine and suddenly I lost domain name resolution.
